In order that the invention may be clearly understood and readily carried into effect, an embodiment of the same is illustrated by way of example in the accompanying drawing, in which 85 Figure 1 is a fragmentary sectional view of a thrust bearing constructed in accordance with the invention, taken between the thrust segments and the thrust collar and seen from the side of the latter, and

40 Figure 2 is a section on the line 2-2 of Figure 1.

The thrust bearing comprises a revoluble part, viz. the shaft (1 and a thrust collar b, thereon, and a stationary part formed by a ring d enclosed by a housing 0. In the ring it are mounted in 45 known manner individual thrust segments e which can tilt about the edge I. The thrust segments e are secured against motion in circumferential direction by intermediate pieces or carriers 0 located between them and held in position 50 on the ring d.

Now, according to the invention, inclined guide ribs h are provided in the intermediate spaces existing between each two thrust segments e, e on the carriers or, preferably by riveting, in such 55 a manner as to extend, in the direction of rotarangement resides in the fact'that the enforced passage, known per se, of the lubricating oil on the slide face of one single thrust segment is obtained by very simple means, viz. by one single guide rib on every carrier 9, both the inner and outer face of the guide rib being operative. With increasing circumferential speed of the thrust collar b, the pressure of the fresh oil accumulated by the guide ribs h before the thrust segments e, e

also increases so that the lubrication eifect is improved automatically without the necessity of increasing the pressure of the lubricating pump. Consequently, the circumferential speed or the shaft and the surface pressure can be increased without reducing the safety of the bearing.

In case the thrust segments e, e are secured in position in the thrust bearing by members other than the carriers 9, the guide ribs It may be fixed to the stationary part of the bearing, for example to the ring (I.

What I claim and desire to secure by Letters Patent is:

1. A thrust bearing with fluid friction comprising a plurality of stationary thrust members spaced from each other, and an inclined defiect- 2 mouse ing member arrangedbetween each two of said thrust members and each adapted both to supply lubricating fluid to the thrust member which follows it in the direction of rotation of the part supported by the bearing, andto lead of! the lubricating fluid from the preceding thrust member.

2. A thrust bearing with fluid friction comprising a stationary part, a plurality of thrust members mounted on said stationary part spacedly from one another, intermediate pieces arranged each in the space existing between each two of said thrust members and adapted to secure them against circumferential shifting motion, and an inclined deflecting member likewise arranged in each of said spaces and adapted both to supply lubricating fluid to the thrust member which follows the respective deflecting member in the direction of rotation of the part supported by the bearing, and to lead ofl the lubricating fluid from the preceding thrust member.

3. A thrust bearing with fluid friction comprising a stationary part, a plurality of thrust members mounted on said stationary part spacedly from one another, intermediate pieces arranged each in the space existing between each two of said thrust members and adapted to secure them against circumferential shifting motion, and an inclined deflecting member provided on each of said intermediate pieces and adapted both to supply lubricating fluid to the thrust member which follows the respective intermediate piece in the direction of rotation of the part supported by the bearing, and to lead off the lubricating fluid from the preceding thrust member.

4. A thrust bearing with fluid friction comprising a stationary part, a thrust collar on the part to be supported by the bearing, a plurality of thrust members mounted on said stationary part spacedly from one another and co-operable with said thrust collar, intermediate pieces each arranged in the space existing between each two of said thrust members and adapted to secure them against circumferential shifting motion, and an inclined deflecting member provided on each of said intermediate pieces so as to tighten toward said thrust collar and adapted both to supply lubricating fluid to the thrust member which follows the respective intermediate piece in the direction of rotation of the part to be supported by the bearing and to lead off the lubricating fluid from the preceding thrust member.

5. A thrust bearing with fluid friction comprising a plurality of stationary thrust members spaced from each other, and an inclined deflecting member arranged between each two of said thrust members and bridging the space between the latter and each adapted both to supply lubricating fluid to the thrust member which follows it in the direction of rotation of the part supported by the bearing, and to lead on the gbricating fluid from the preceding thrust mem- 6. A thrust bearing with fluid friction for a rotary member comprising a stationary part, a plurality of thrust members mounted on said stationary part with intermediate spaces between one another, means for securing said thrust members against circumferential shifting movement, and an inclined deflecting member in each of said spaces adapted both to supply lubricating fluid to the thrust member which follows the respective deflecting member in the direction of rotation of said rotary member supported by the bearing, and to lead of! the lubricating fluid from the preceding thrust member.

7. A thrust bearing with fluid friction for a rotary member comprising a stationary part, a plurality of thrust members mounted on said stationary part with intermediate spaces between one another, said thrust member adapted to be stationary in a circumferential direction, an annular channel for fresh lubricant adjacent the internal boundary of said thrust members, an annular channel for the used lubricant adjacent the external boundary of said thrust members, an inclined deflecting member in each one of said intermediate spaces having a damming edge abutting said rotary member and extending in the direction of rotation of the rotary member from the exit side of one thrust segment at the point thereof adjacent said fresh lubricant channel to the entrance side of the following thrust segment at the point thereof adjacent said used lubricant channel, whereby each deflecting member both supplies the fresh lubricant to each thrust segment and leads of! the used lubricant from the preceding thrust segment.
